example

Copy test to directory dir1

$install test dir1

Here, copy the test file to dir1 directory. If there is test in dir1, it will be replaced; directory will not be automatically created. dir1 must already exist, otherwise test will be copied to dir1 file.

Create dir2/dir21/directory

$install -d dir2/dir21

This will create a dir2/dir21 directory, if it exists, it will not be overwritten, if it does not exist then create such a multi-level directory.

Copy test1 test2 files to dir1 directory

$install -t dir1 test1 test2

Here, copy the test1 and test2 files to dir1 directory, if there is no directory will not be automatically created.
